| Description | An item or element of a randomization book that is used to assign an experimental unit to a planned arm or portion of an arm in a study. For example: An entry might be mapping the 5th experimental unit in a given Stratum Group to a particular treatment Arm. A randomization book is a predefined set of assignments to portions of a study based on criteria, such as stratum group for example, that ensures a desired distribution of experimental units across those portions of the study. For example, the book entries indicate which arm a given experimental unit, Joe, is assigned to based on the fact that he's the 5th experimental unit in stratum group #2. |
